WebGLUniformLocation - Web APIs 编辑

The WebGLUniformLocation interface is part of the WebGL API and represents the location of a uniform variable in a shader program.

Description

The WebGLUniformLocation object does not define any methods or properties of its own and its content is not directly accessible. When working with WebGLUniformLocation objects, the following methods of the WebGLRenderingContext are useful:

• WebGLRenderingContext.getUniformLocation()
• WebGLRenderingContext.uniform()

Examples

Getting an uniform location

var canvas = document.getElementById('canvas');
var gl = canvas.getContext('webgl');

var location = gl.getUniformLocation(WebGLProgram, 'uniformName');
